Step-by-Step Instructions
1
Prepare the Surface
- Clean the entire surface of the retaining wall, including the footing.
- Scrape away any dry concrete spillages.
- Use a leaf blower to remove any dust and ensure the surface is clean and debris-free.
2
Reinforce Cracks and Vulnerable Areas
- Pre-cut Geo-Textile to fit cracks, gaps, holes, and corners.
- Ensure to cut a 150mm strip of Geo-Textile for the entire wall-floor join.
- Apply a coat of Waterproof Sealant to these areas using a brush, and embed the Geo-Textile into the wet sealant. Smooth out any air bubbles or wrinkles for a perfect bond.
3
Apply the First Coat of Waterproof Sealant
- Apply the first coat of Waterproof Sealant to the entire retaining wall surface, using an up-and-down motion to ensure even coverage.
- Use ample product to achieve a uniform layer, especially over reinforced areas.
4
Apply the Second Coat of Waterproof Sealant
- Once the first coat has cured, apply a second coat using a left-to-right motion. This ensures thorough coverage and creates a durable waterproof barrier.
- Aim for a dry-film thickness of 1.5mm (approximately 2 liters per square meter).
5
Optional: Speed Up with Rapid Cure Spray
Use Rapid Cure Spray to set the product instantly and reduce curing time. Ensure the spray is fully dry before applying additional coats.
6
Cure and Protect Before Backfilling
- Allow the Waterproof Sealant to cure for 48-72 hours before applying protection boards (corflute).
- Before backfilling, add gravel and ag-pipe to improve drainage and prevent water pooling against the wall.
